Abstract: PROBLEM TO BE SOLVED: To prevent input connection of a disturbing signal to a conductor between a switch element and a seatbelt fastening device so as to dispense with a high performance switch element by connecting the switch element with an ignition element in parallel. SOLUTION: An ignition element is constructed of a resistor 10 and a capacitor 11 connected in series, and a switch element 13 is connected to the ignition element in parallel, while another resistor 12 is connected to the switch element 13 in series. A resistor 16 connected to the switch element 13 in parallel is used for recognition of disconnection. As the switch element 13 is normally closed, a current circuit informs that a seatbelt is not inserted into a buckle for recognition of a seatbelt operating state. When a seat belt is mounted, the current circuit is cut off. In this way, symmetric wiring protective against input connection of an electromagnetic disturbance can be accomplished. As ignition current for ignition elements 10, 11 is not needed to flow via the switch element 13, a low-cost switch element 13 for low current can be used.

After that, the water in the individual processing tank 21 of B is discharged, the wafer W is pulled out and put into an individual processing tank 21 of C. NH4OH and H2O2 are supplied to the tank C, and the surface of the wafer W is washed. After a specified time has passed, the liquid in the individual processing tank 21 of C is discharged, and the wafer W is pulled out. The wafer is put in an individual processing tank 21 of D, and pure water is supplied and overflowed. After washing, the water is discharged, and the wafer is taken out, thereby finishing the washing process.

Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To restrain the sticking among scraps during heating and to improve heat efficiency by using wood as a void material in scrap packing layer, at the time of heating the iron scrap in a melting furnace of a preheating furnace. SOLUTION: At the time of charging the iron scrap into the melting furnace 1 or the preheating furnace 6, the wood 3 is mixed in the range of 0.02-0.15wt.% with the charged scrap 2. The used wood at this time contains 20-50wt.% moisture. Since the wood is burnt or carbonized during preheating by charging the wood mixed with the scrap and the bulk is reduced, the void ratio in the scrap packing layer is increased and gas ventilation is improved, and at the same time, the produced charcoal and wood ash prevent the mutual sticking among the scraps. Further, the used wood is desirably crushed edge wood and waste wood dismantled, developed at the time of building work. By this method, the treatment of the waste wood not problematic to the environment and the effective utilization of combustion energy can be executed.
